Switzerland led twice in the first half in Basel, but was pegged back on both occasions, before Wirtz curled a delightful effort over Gregor Kobel to put Germany ahead in the 61st minute.

Young Boys forward Joel Monteiro hammered beyond Oliver Baumann from distance after stepping off the bench, but that parity was short-lived as another pinpoint finish from Wirtz extended Germany's winning streak to six matches.

Kobel made a good stop to deny Kai Havertz in the 14th minute, and shortly afterwards, Switzerland went ahead through Dan Ndoye's near-post finish, which came after a mazy run inside from the left.

Jonathan Tah equalised with a back-post header from Wirtz's cross, but the Bayer Leverkusen defender was then bullied all too easily for Switzerland's second goal, as Breel Embolo got ahead of him to connect with Silvan Widmer's cross.

Things almost got worse for Germany as Fabian Rieder rattled the crossbar, but in the final action of the first half, Serge Gnabry beat Manuel Akanji to Wirtz's through-ball before dinking a delicate finish over Kobel.

Those same two players combined when Julian Nagelsmann's side took the lead for the first time, with Wirtz looping a superb strike in off the underside of the crossbar after collecting Gnabry's short corner from the left.

It looked as though Switzerland might avoid defeat when Monteiro levelled with a rasping effort in the 79th minute, but just six minutes later, Wirtz found the same corner again in composed fashion after good work from Pascal Gross on the right flank.

Wirtz, who missed the 2022 FIFA World Cup through injury, has been struggling for form in his first season at Liverpool but played arguably his best game for the national team here.

"Well with four scorer points, most likely, yes," Wirtz said.

"We have a tight [FIFA] World Cup phase in front of us and we obviously want to reach the final and win the trophy but we all know it will be a very hard road until then."

As for the three goals conceded, Wirtz said it was part of the process of coming together as a team.

"No concerns there because we have a very good team and a good defence," he said.

"I think you feel that we have not played together for some time and all three goals were a little bit avoidable. But it is about winning games and if you score more goals than the opponent then it's all right."
